Abstract

The invention discloses a composite fertilizer and a preparation method thereof. The invention is characterized in that the fertilizer is prepared from the following raw materials in parts by weight: 65-85 parts of urea, 45-65 parts of monoammonium phosphate, 30-50 parts of potassium sulfate, 300-350 parts of straw, 300-600 parts of animal manure and 9-12 parts of soil activator. The composite fertilizer is simple to operate, and has the advantages of reasonable raw materials and rich nutrients; the soil conditioner contains the bowlder component, the bowlder component contains abundant minor elements which are beneficial to the human body, and the minor elements are absorbed by the crops and converted by the food chain, are beneficial to the human body; and the fertilizer contains the adsorption component capable of effectively adsorbing and solidifying toxic heavy metal elements in the soil, thereby reducing the heavy metal elements absorbed by the crops and enhancing the crop yield.

Description

technical field [0001] The invention relates to a fertilizer and a preparation method thereof, in particular to a combined fertilizer and a preparation method thereof. Background technique [0002] Agriculture is the foundation of other industries such as industry and service industry. The rise and fall of agriculture is a major event that directly affects the national economy and people's livelihood. At present, the world is facing severe problems of population increase and environmental degradation. As a country with a large population and a large agricultural country, this problem is particularly prominent. One of the main reasons for this situation is the extensive use of inorganic fertilizers. The deficiencies of this inorganic fertilizer are mainly manifested in the following aspects: 1. The nutrient is single and cannot provide comprehensive and reasonable nutrients for crops; 2. After use, the soil will be acidified or salinized, which will reduce the soil quality; ...
